Hei wāhanga nui o te whānuitanga o ngā taputapu, taonga me ngā taputapu, he pānga nui te rauemi me te mahi a ngā wīra ki te kounga me te mahi a te hua whānui. I roto i ngā momo wīra maha, ko ngā wīra TPR me ngā wīra rapa BR ngā whiringa e rua. I tēnei rā ka whakatauritehia ngā rerekētanga i waenga i ēnei momo wīra BR me tpr e rua.
Ngā Rauemi me ngā Āhuatanga
Tuatahi, he mea hanga ngā wira TPR ki te rapa kirihou wera (TPR), he rauemi kirihou wera he ngāwari te rapa, kāore e hiahiatia kia whakamomonatia, ā, he pai mō te taiao, kāore he paitini, he kanapa hoki te tae. Nā te ngāwari me te ātete ki te pakū o te rauemi TPR, he pai te ātete o ngā wira TPR ki te pakū, ki te hinu me te huarere.
He rerekē, ko ngā wira rapa BR he mea hanga mai i te rapa butadiene (BR), he rapa hangai i hangaia mai i te whakakotahitanga o ngā monomers butadiene, ko tōna hanganga ngota he rite ki te rapa maori. He pai te ngāwari o te rapa BR, te ātete ki te pakū, te ātete ki te makariri, me te ātete ki te piko.
Te tukatuka me te mahi
He pai ake te mahi tukatuka o te rauemi TPR i tērā o te rapa, ā, ka taea te tukatuka mā te whakamahi i ngā taputapu tukatuka kirihou wera noa, me te kore he maimoatanga whakamomona motuhake. Mā tēnei ka nui ake te whai huatanga o ngā wīra TPR, ā, ka iti ake te utu ki te whakaputa.
Heoi, he tino pai ngā wira rapa BR ki te mahi hihiri, inā koa i ngā pāmahana teitei. He tino pai te ātete o te rapa BR ki te pakū, te ātete ki te poka, me te ātete ki te haehae hihiri, e āhei ai ngā wira rapa BR ki te pupuri i te mahi pai i roto i ngā taiao uaua.
Te tiaki taiao me te haumaru
Mō te tiaki taiao, he painga tō te rauemi TPR: he rauemi pai mō te taiao, kāore hoki he paitini, e tutuki ana i ngā paerewa ROHS, REACH me ētahi atu paerewa taiao, ā, ka taea te whakamahi whānui i roto i ngā taputapu hauora, ngā taonga takaro a ngā tamariki me ētahi atu mara. He rerekē, ahakoa he rauemi pai mō te taiao te rapa BR, tera pea ka herea e ngā ture taiao i roto i ētahi āhuatanga tono.
I te wā e whiriwhiri ana i ngā wira hurihuri, me whai whakaaro whānui i runga i ngā āhuatanga pēnei i ngā horopaki tono motuhake, ngā whakaritenga mahi me ngā ture taiao. Hei tauira, he pai ake pea ngā wira hurihuri TPR i roto i ngā horopaki e hiahia ana ki te hua nui, te utu iti me ngā whakaritenga taiao teitei, ko ngā wira hurihuri rapa BR ia he pai ake pea i roto i ngā horopaki tono e hiahia ana ki te mahi hihiri teitei ake me te ātete pāmahana teitei.
